Patent TW-558765-B (TW)
Title: Integrated post-etch treatment for dielectric etch process
Inventor: OU YANG-HUEI
IPC: H01L21/768
Filed: 2000-05-16
Granted: 2003-10-21
Abstract: The present disclosure pertains to an integrated post-etch treatment method which is performed after a dielectric etch process. Using the method of the invention, byproducts formed on the sidewalls of contact vias during the dielectric etch process can be removed efficiently. The method of the invention also reduces or eliminates the problem of polymer accumulation on process chamber surfaces. An overlying photoresist layer and anti-reflection layer are removed during the performance of the post-etch treatment method. Typically, after the etch of a dielectric material to define pattern or interconnect filling spaces, a series of post-etch treatment steps is performed to remove residues remaining on the wafer after the dielectric etch process. According to the method of the present invention, a post-etch treatment method including one or more steps is performed after the dielectric etch process, preferably within the same processing chamber in which the dielectric etch process was performed. The post-etch treatment method comprises exposing a semiconductor structure to a plasma generated from a source gas comprising oxygen, a nitrogen-comprising gas, and a reactive gas comprising hydrogen, carbon, and fluorine. Two optional steps, a flushing step prior to the post-etch treatment and a cleaning step subsequent to the post-etch treatment, can be performed for the purpose of enhancing the fluorine and byproduct removal and post-etch chamber cleaning.

Title: Manufacturing process of polymer structure of microsphere and micrononsphere array by excimer laser
Inventor: TSAI HUNG-YING
IPC: G03F9/00
Filed: 2000-07-20
Granted: 2002-08-21
Abstract: This invention provides a manufacturing process of polymer structure of microsphere and micrononsphere array by excimer laser using a photomask having a predetermined curve line pattern whose width is not constant along the direction of a straight line. The light of the excimer laser passes through the curve line pattern of the photomask and impacts the polymer material coated on a substrate to peel and etch the polymer material. The substrate moves along the direction perpendicular to the straight line during excimer laser emission to make the polymer material receive emission of different durations of time at different positions along the direction of the straight line and thus create different etching depths. Therefore, the polymer material is etched into a three-dimensional pattern of a predetermined shape. Moreover, through two times of emission etching of different directions or different photomask pattern, a micro array structure of quasi-sphere or nonsphere can be obtained.

Title: Method for recovering and producing C4-C6 dicarboxylate from alkaline waste solution generated in caprolactam preparation process
Inventor: JOU SHIAN-JIUN
IPC: C07C55/14
Filed: 2001-08-14
Granted: 2003-09-21
Abstract: The present invention relates to a method for recovering and producing C4-C6 dicarboxylates from an alkaline waste solution generated in a caprolactam preparation process, in which the alkaline waste solution is neutralized with sulfuric acid to adjust pH value and separate into an aqueous phase and an organic phase, allowing valuable substances contained in the organic phase to be firstly oxidized by introducing nitric acid as an oxidation agent and converted into dicarboxylic acids. Then, the dicarboxylic acids is introduced into a two-stage concentration apparatus. The first-stage concentration is to distill out low boiling-point monocarboxylic acids and most nitric acid. In the second-stage concentration, remaining nitric acid and nitrocompounds are decomposed at higher temperature to recover most nitric acid, and thus crude concentrates mainly comprising C4-C6 dicarboxylic acids are obtained. The concentrated crude product is added with C1-C4 alkyl alcohols to proceed a two-stage esterification, during which the first stage obtains intermediates by which half of carboxylic acid groups being esterified, and the second stage obtains highly esterified crude dicarboxylates. The crude dicarboxylates receive a distillation process, so as to produce single-species dicarboxylates or a mixture of at least two species of dicarboxylates, which can be used as non-toxic environmental solvent or ingredients of diols. This therefore provides an efficient oxidation and improved concentration method for effectively recovering most valuable substances from the alkaline waste solution, so that economic benefits in recovery are greatly raised.
